Andrew Residence Ultrex Casement Windows

Builder: Randy Burton of Burton Builders

Distributor: Super Enterprises

This 1928 Clinker Brick Tudor style cottage sits just three blocks from the Atlantic Ocean. The owner of the home wanted to update the home while matching the charm that had existed for over 85 years. In order to match the architectural style and meet the performance requirements of a coastal environment, Integrity windows and doors were chosen for the project. The Integrity product offerings allowed for brand new casement windows with a divided lite design that replicated the 85 year-old wood windows. The home also now features a two story glass wall that overlooks the outdoor living space, providing a seamless transition between home and nature.
